I'nonIA, ILLINoIs Y i TWISTING TOOL Applicationled March22, 1929. Serial No."349,190.

This `invention has reference to twisting tools, and it has for its principal object to provide a tool for manual operation which may be quickly and efficiently applied to a wire fastener for securing the stringer elements of a revetment, such for instance as the stringer elements employed in connection y with anarticulated concrete mattress used to derstood, reference is had to the accompanying drawings forming part of this description, illustrating a preferred embodiment of the invention, in which 1.--

Fig. 1 is a view in elevation, on a reduced scale, showing atwisting tool embodying my invention;

Fig. 2 is a detail in elevation, partly in section, showing the manner of applying the twisting portion of the tool to a wire fastener Y which is shown in dotted lines;

Fig. 3 is a view similar to Fig. 2 and of the same parts, except that nthe fastener, shown in dotted lines, is secured in twisting position in the tool; p

Like characters of Areference denote corresponding parts thruout the figures.

The fastener A shownin dotted lines in Figs. `2, 3 and 4, is the fastener forming the subject matter of my companion application l bearing SerialNo." 349,191, and isformed ,from a single length of wire bent on itself to provide the'arcuate bend a from which extend thelegs b and c, the former shorter than the latter and the ends of each leg formed with the right angle bends cl and e, respectively. The bend Z on the leg turned away from the leg c and the bend e on the leg o turned toward the leg b and having a relation so as to provide the throat f therebetween. y

The tool adapted for twisting the legs b land c with each other, as at g in Fig. 4, to secure the stringer element-s 71. of a revetment comprises a stem 1, of suitable length to which is connected and extends therefrom a holder 2. In one form the stem' 1 has a hand-hold 3 for manual gripping whereby to turn the tool for twisting the legs b and o of the fastener A. In another form, see Fig. 7, the stem 1 is provided thruout with a double thread 4 cut therein and slidable on the stem is a sleeve 5 having a hand-hold 6 and interiorly disposed nuts or members 7 operative in the threads 4, so that as the sleeve 5 is moved along the stem and the nuts or meinbers 7 caused to traverse the threads 4, the tool is turned, as will be understood.

The holder 2 is preferably an elongated substantially Vflat channel-like member having two side walls 8, with one side open, as at 9, and with a rear wall 10 extending down from the stem to a point removed from the lower end of the holder, as at 11, leaving the lower end of the holder open between the side walls 8, 8, see Fig. 2. A bridge member 12, which is preferablyinclined to the axis p truding stops 13, to limit the downward movement of a sleeve 14 embracing and slidable onthe holder 2. That wall of the sleeve 14 coincident withthe open side 9 of the hold-` er has .the rounded or beveled lower inner portion 15. p Provision is made to hold the sleeve 14 in twisting and non-twisting positions on' the holder 2, which consists in providing the outer faceof one of the side walls 8 of the holder 2, near the upper and lower ends thereof with'ball-seats 16, see Figs, 1, 3, 5 and 7 ,and

adapted to coact with and become seated in said seats, is a ball-lock 17 yieldingly held by a spring 18 disposed in abase 19 projecting laterally from the face of the holder, see Fig. 5. It is obvious, therefore, that the sleeve 14 maybe caused to have a slidable movement on the'holder toward and from the stem 1 and be held in these different positions by the ball-lock 17, becoming seated in a ball-seat 16. The spring 18 applies the necessary force to hold the ball in a seat to lock the sleeve buty will yield readily to pressure applied to the sleeve to move it to its different positions, as shown in the kseveral figures. A stiffening member 2O is disposed transversely within the lholder Qconnecting the side walls 8, mi dway the length 'of the holder 'and yet out of way to avoid interference Vwith the ap- -plic'ation of theto'olto a fastener A.

To use the tool to apply a fastener A for f se'curing the Stringer elements h of a revetment, such as is iliilstrated in my companion application bearing Serial No. 349,189, the fastener is first applied to the Stringer h, by

Ypassin the long legb under the stringer,

which' atter enters the throat of the fastenj'er and is Aseated inthe arcuate end of the fastener between the le b and 0 thereof. A person handling the tool will first see that "the sleeve 14 is in non-twisting position ,shown in .Fi/g. 2 and yon applying the twisting head 2 tothe lfastener, the legs of the fastener atrecause'dto enterthe open side9 of the head w'thlt-he angular end yd overlying the bridge "QaIIdthe angular end e resting against the "Wall 10,s'ee Fig. 2. f With the fastener in this position in the head 2 of the'tool, the sleeve f14isinoved downwardly into twisting position until brought to rest on the stops 13 and during such downward movement of the jsleeve 'the rounded or beveled portion 1-5 of 'the sleeve will lride .against the leg c of the vfastener and cause the fastener to assume the position shown in Fig. 3, withthe'throat f, partially formed bythe angular end Z and the straight body 4portion ofthe lleg 0, practical'lyclosed. In 'this position the angular ends dand e lie in the sleevef14 between the 'side' wal-ls'S, and this sp'acebeing .a shallow space, the ends of Ithe fastener cannot slip or 'turn and when fthe tool is turned,the arcuate end -o'f the 'fastener being anchored against 'the Stringer elements h, .the'turning of the 'head and sleeve will apply force against the 1,angularends of the fastener and cause a twisting ofthelxegs b and c together, as at g, see Fig. 4. -ien the vtwisting action is completed, 'the sleeve 14 is vmoved to non- -twisting V,position ,permitting the head 2v2 to vbe easily and conveniently removed from :the secured fastener. The Vwall 10 is cut-off short of thelower end of the tool so that there is nothing to interfere with `or retard the placing of the angular end al of the fastener over 'thebridge 12 and the wall 10 -endsof a fastener therewithin, and a member having movable relation with respect to the head and adapted to engage and secure a 'fastener in a twisting position on the head. f2. A twisting tool for securing wire fasteners to revetment work, comprising a slotted head adapted to receive twisting ends of a fastener therewithin, and a member slidable on the head adapted to lengage and secure a fastener in twisting position.

3. A twisting tool for securing wire fasteners to revetment work, comprising la head slotted along one edge and at its end to receive a fastener therewithin, va wire engaging bridge crossing said slotted end, and ameniber slidable on the head and having a wall adapted to be moved across 'the slotted edge of said head and to bear against the fastener to secure the same in twisting position in the head.

4. A twisting tool for securing wire fasteners to revetment work, comprisin a shallow elongated head having two si e walls 'of a wire fastener therebetween, a member slidable on the head adapted to engage and secure a fastener in twisting position, and means complementary to the head and `member, 'whereby the member and head may have a locking relation in dierent positions of the member.

6. A twisting tool for securing fasteners tofrevetment work, comprising a slotted head adapted to receive twisting ends of a fastener `therewithin, a Ahandle for turning said head, and a member having va slidable and telescopic movement on said 'head adapted to engage and secure a fastener in twisting position in said head.

7. A tool for securing wire fasteners to .revetment work, comprising a shallow elongated head slotted along kone edge and at its 'end to receive the spaced ends of a preformed wire fastener vtherewithin, a bridge across they slotted end-of the head to receive one end of the fastener, and a rmember telescopically slidable on said Ahead and'having a wall adapted to overlie the slotted edge of the head and engage another end of the fastener, whereby to secure said fastener Within the head in twisting position.

8. A tool for securing wire fasteners to revetment work, comprising a shallow elongated head slotted along one edge and at its end to receive the spaced ends of a preformed wire fastener therewithin, a bridge across the slotted end of the head to receive one end of the fastener, a member telescopically slidable on said head and having a wall adapted to overlie the slotted edge of the head and engage another end of the fastener,

whereby to secure said fastener within the head in twisting position, and means complementary to the head and member, wheren. by the member and head may have a locking relation in dilferent positions of the member.
